Answer:

Step-by-step explanation:

Q no 4 :

4, 8

1, 5

3, 7

2, 6

Q no 5:

(a)

10x + 1 = 12x - 5

1+5= 12x - 10x

2x = 6

x = 6/2

x = 3

(b)

11x - 15 + 5x - 13 = 180 (angles on a straight line)

11x + 5x - 15 - 13  =180

16x - 27 = 180

16x = 180 + 27

16x = 207

x = 207 / 16

x = 12.9375

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. Determine the length of the radius.
Viefleur [7K]

Answer:

see explanation

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 4)² + (y + 6)² = 16 is in this form

with r² = 16 ⇒ r = \sqrt{16} = 4

---------------------------------------------------------------

given (h, k) = (5, 2) and r = 20, then

(x - 5)² + (y - 2)² = 400 ← represents the delivery area
